Abstract

A method and apparatus for controlling scanning of radio channels by mobile stations in a cellular radiotelephone system, including transmitting from a base station a control signal, e.g., a battery savings order, to a group of mobile stations for informing the group of mobile stations that no pages will be issued directed to them for a predetermined period, upon receipt of which the mobile stations begin scanning during the predetermined period radio channels to identify which radio channels have superior characteristics, and storing the channels identified to have superior characteristics for later use as respective access and control channels.
